SPEAKER:
Research on mobile microrobots has been on going for the last 20 years\, but the few robots that have walked have don e so at slow speeds on smooth silicon wafers. However\, ants can move at s peeds over 40 body lengths/second on surfaces from picnic tables to front lawns. What challenges do we still need to tackle for microrobots to achie ve this incredible mobility? This talk will discuss some of the mechanisms and motors we have designed and fabricated to enable robot mobility at th e insect size scale as well as the use of microfabrication to improve larg er robots. Mechanisms and sensors utilize new microfabrication processes t o incorporate materials with widely varying moduli and functionality for m ore complexity in smaller packages. Actuators are designed to provide sign ificant improvements in force density\, efficiency and robustness over pre vious microactuators. Results include a 4mm jumping mechanism that can be launched approximately 35 cm straight up as well as a 300mg robot that jum ps 8 cm with on-board power\, sensing\, actuation and control.< /SPAN>
